“The Diffraction Grating Is A Useful Device For Analyzing Light Consists Of A Large Number Of Equally Spaced Parallel Slits.”Its Working Principle Is Based On The Phenomenon Of Space Between Lines Act As Slits And These Slits Diffract The Light Waves Thereby Producing A Large Number Of Beams Which Interfere In Such A Way To Produce Spectra.

Diffraction Grating Handbook - Chapter 1 . THE GRATING EQUATION [top] When Monochromatic Light Is Incident On A Grating Surface, It Is Diffracted Into Discrete Directions. We Can Picture Each Grating Groove As Being A Very Small, Slit-shaped Source Of Diffracted Light. The Light Diffracted By Each Groovebines To Form A Diffracted Wavefront.
In Optics, A Diffraction Grating Is An Opticalponent With A Periodic Structure That Splits And Diffracts Light Into Several Beams Travelling In Different Directions. The Emerging Coloration Is A Form Of Structural Coloration. The Directions Of These Beams Depend On The Spacing Of The Grating And The Wavelength Of The Light So That The Grating Acts As The Dispersive Element.

Holographic Gratings From Gratingworks Have A Groove Density From 40 To 6000lines/mm And Cover A Wavelength Range From Fringe Profiles Of Gratings Can Be Sinusoidal, Deformed Sinusoidal, Or Triangular. Their Diffraction Efficiency Is From 30% To 85% At Their Optimized Wavelength. If Only TM Polarization Is Desired, The Diffraction Efficiency Can Reach 95%.

Diffraction Grating Physics. Diffraction Gratings Are Used To Disperse Light; That Is To Spatially Separate Light Of Different Wavelengths. Figure 4: The Sign Convention For The Angle Of Incidence, Angle Of Diffraction And Grating Angle. If The Angle D Is Equal To I And Of Opposite Sign, Then The Grating Angle And Order Are Zero, And The
